1975 4 speed transmission help

I am trying to put new synchros and input shaft in a 1975 4 speed. I can't figure out how to get the reverse sliding gear off the shaft. I have removed the roll pin on the output shaft and all of the snap rings. I can get all of the gears to spread apart so I can clearly see the gear in question, but it will not budge. Is it pressed on?
Thanks

I finally figured it out. First one of these I have torn apart and I wasn't tilting it down far enough. Once I figured it out, it was a DUH. Looks like getting the needle bearings back between the input and output shaft will be fun. I'll need some bubble gum grease for that.
